Hello snobs 
About a week ago my ECM Mechanika Slim began an issue. On the initial morning startup the boiler doesn’t get to temperature and sort of stops/idles at a very low temp not enough pressure build up to run the steam or water wands. I can correct this by fiddling with it (turning off/on, running the brew head, pulling the water reservoir and reinstalling (the water reservoir seems to have the best success in this)). Subsequent startups later in the morning have mixed result in whether it gets to temp or not.
I’ve noticed that when working and in its 15–20 minutes warmup phase, there’s a distinct quiet-to-loud sort of pressure release rumble that sounds like it comes out of the top of the boiler, and sounds like a miniature Kelly boiling. This happens in the first maybe 5 minutes of the heat up phase and lasts about 6–7 seconds and ends abruptly. This last week the machine stops heating before I hear this noise, and once I get it running again this noise happens within a minute or so.
To troubleshoot, I’ve given it a good water backflush and cleaned the reservoir in case the little magnet float valve thing wasn’t working properly but hasn’t solved the issue.
Any ideas as to what might be beginning to fail?
I maintain the machine well, and pull ~4 shots a day with twice-filtered rainwater (soft water).
Any help of what to check for is appreciated! I have a family event in a couple weeks which I want the machine working for
Cheers!
